lUNITED STATES PATENT OFFICE 2,532,979 DEVICE FOR SANDING FLOORS OR THE lLIKE Nathan B. Wilson, Savannah, Ga. I

Application June 10, 1949, Serial No. 98,370

(Chill- 187) 17 Claims. l

This invention is a novel improvement in devices for manually waxing, sandpapering, or polishing floors or the like, and the principal object thereof is to provide a device which will be simple and efcient, same consisting of a minimum number of parts secured together in the novel manner, and including a hinged handle which can be rotatorily adjusted on the top of the device so as to extend therefrom in different angular positions.

Other minor objects of the invention will be hereinafter set forth.

I will explain the invention with reference to the accompanying drawing, which illustrates one practical embodiment thereof to enable others to adopt and use the same; and will summarize in the claims, the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawing:

Figure 1 is a perspective view of a device embodying my invention.

Fig. 2 is a vertical sectional view in perspective, on line `2 2, Fig. 1, but showing the handle removed from the base, to better illustrate the construction.

As shown, my novel device consists of a base member comprising a plate I, of rectangular shape, the peripheral edges of the plate being bent back upon themselves as at Ia, and the edges being further bent upwardly as at Ib,'inset from the outer edges of the bent portions Ia. The upturned portions Ib at the short edges of the plate I are then further bent outwardly as at Ic to form lips overlying the portions Ia, same being disposed parallel therewith but spaced therefrom, as shown in Fig. 2. The upturned portions Ib at the longer edges of plate I have their ends Id (Fig. 1) flanged to overlie the upstanding portions Ib of the short edges and are soldered, welded, or otherwise secured thereto to form a rigid unit.

Within the u'pstanding portions Ib of the plate I is a plate 2 having its short edges flanged downwardly as at 2a. so as to seat squarely within and against the upstanding portions Ib of the short edges of plate I, the flanges 2a being secured to y the upstanding members Ib by means of countersunk screws 3 or the like Iwhich Ipass through holes in the upstanding portions Ib and through registering perforations in the ilanges 2a and which engage nuts 4 which are soldered to the inner faces of the flanges 2a, as shown in Fig. 2, thus securely locking the plate 2 within the plate I. In the plate 2 are a series of holes 2d arranged in circular formation on a pitch circle coaxial with the center of plate `2, eight such holes being shown in the drawing, and soldered on the underside of plate 2 opposite each of the holes 2d are nuts 6 (Fig. 2) for the purpose hereinafter described.

Around the upturned portions Ib of plate I between the return bent portions Ia and the lips I c is a clamp member formed in sections, each consisting of a strap I bent to extend around a corner of the base I, with its ends terminating substantially at the mid points of the two adjacent sides of the corner, the ends of the strap 'I being outturned as at la., and the outturned portions being perforated to receive screws or bolt 8, whereby the sections of the clamp can be tightened around the base I. Obviously, the number of sections I of the clamp may be changed, as desired.

When the clamp 'I is removed, the base may be placed upon a sheet of fabric F, on the ulpper surface of which has been placed a desired amount of wax W of area equal to the lower face of the plate I, and the edges of fabric F are then turned upwardly to c-verlie the upturned portions Ib and are secured together by the bolts or screws 8 so as to securely clamp the fabric F to the base. Before applying the clamp l, the upper edge of fabric F may be held in approximate position by the use of an elastic or lacing tape 'I' (Fig. 2) thereby facilitating the application of the clamp 'I.

The handle il! has its lower end secured by screw threads or the like in a socket I la of a socket member I I carrying a hinge pin I Ib extending at right angles thereto, said pin IIb being secured in hinged sockets I2 connected by screws I3 to a plate lf3 of greater length than the pitch diameter of the holes 2d, the same being provided with bores to receive machine screws I5 or the like, which may be threaded into any pair of diametrically opposed holes 2d. Obviously, by reason of the above arrangement, the handle I0 may be given any desired angularity with respect to the base depending upon in which pair of holes 2d the machine screws I5 are engaged, the screws entering the nuts 6, which are soldered to the plate 2 below each of the holes 2d.

Instead of using fabric F and wax W, it is obvious that a sheet of sandpaper may be similarly applied to the base, and the device thus used for sandpapering oors or the like, the same holding the sheet of sandpaper rmly thereto.

I do not limit my invention to the exact form shown in the drawing, for obviously changes may be made therein within the scope of the claims.

l. A device of the character specified; comprising a base plate of rectangular shape having its edge portions turned back upon themselves and further turned upwardly normal to the plate; a second plate having downturned flanges at its edges closely fitting between and against the upturned portions of the base plate and secured thereto, a contractible clamp member around the upturned portions of the base plate adapted to clamp a exible sheet between the upturned portions and clamp member; and a handle secured to the second plate.

2. In a device as set forth in claim 1, said clamp member comprising sections each embracing a corner of the base and extending to points adjacent the middle of adjacent edges of the base, the ends of the sections being outturned and perforated; and bolts adjustably connecting the outturned ends.
